6. Remove Old Thermostat A standard heat cool thermostat consists of three basic parts 1 The cover which may be either a snap on or hinge type 2 The base which is removed by loosening all captive screws 3 The switching subbase which is removed by unscrewing the mounting screws that hold it on the wall or adapter plate Before removing wires from old thermostat label each wire with the terminal designation from which it was attached Disconnect the wires from the old thermostat one at a time Do not let wires fall back into the wall Installing New Thermostat 1 Pull the thermostat body off the thermostat base Forcing or prying on the thermostat will cause damage to the unit Place base over hole in wall and mark mounting hole locations on wall using base as a template Move base out of the way Drill mounting holes If you are using existing mounting holes and the holes drilled are too large and do not allow you to tighten base snug ly use plastic screw anchors to secure the base Fasten base snugly to wall using mounting holes shown in Figure 2 and two mounting screws Leveling is for appearance only and will not affect thermostat operation Connect wires to terminal block on base Push excess wire into wall and plug hole with a fire re sistant material such as fiberglass insulation to prevent drafts from affecting thermostat operation Carefully line the thermostat up with the base and snap into place Bat
